This is one of those times when a sense of humor can be really, really helpful...
Since the only person you can actually change is you...think of ways to change your reactions to his digs. If you answer with a snappy comeback, it will diffuse the tension, and your feelings won't get so easily hurt. Obviously Anthony thinks you're a good person too....that's why he married you. You could remind him that he picked his son's mother (you), and compliment him on his good taste!
You did turn out good!!! This sounds like one of those stupid comments men sometimes make without thinking. Don't let his comments make you feel insecure--just give him a playful verbal jab right back. The best way to diffuse a potentially hurtful situation like this is to keep things light.
Anthony has stuck with you through thick and thin...I think this was just an offhand comment that he probably thought would be funny, but it fell flat. Brush this one off, and be ready with a quick comeback next time.
